We have an extensive Hillyer ancestry from the Hillyers who settled in Connecticut River valley (Simsbury, CT; Windsor, CT; Granby, CT; Longmeadow, MA) in the 1600s and moved to Georgia around 1800.
These are descendants of John Hillyer, who came to Windsor, CT "as early as 1639" according to the Junius Hillyer book cited below, and died July 16, 1755.Shaler Hillyer moved from Simsbury to Georgia around 1800.His descendants include Junius Hillyer, who was a member of Congress, solicitor of the US Treasury just before the Civil War, and judge; and George Hillyer (Sr.), who fought at Gettysburg, was mayor of Atlanta, and a judge.That George Hillyer was my great-great-grandfather.
A book, "The Life and Times of Judge Junius Hillyer (from his memoirs)" printed 1989 by Boyd Publishing Company, Tignall, GA, has a lot on the GA Hillyers and their CT antecedents.
"Rambling Rose," by Carter Willingham, and the film starring Laura Dern, is by a relative & a fictional account of a Georgia family called the Hillyers.
Hillyer names survive in our direct family mostly as first and middle names: Hillyer Young and Asa Smith (Asa is an old Hillyer first name) are cousins, Forrest Hillyer Quaid Sullivan and Jon Hillyer Jurgovan are nephews.
